The Next Breakthrough Is Here: Achieve Corded Power with the New M18 FUEL™ Circular Saw

The NEW M18 FUEL circular Saw not only generates the power of a corded saw, but also cuts faster than the leading corded units available in the industry. With increases in overall power and run-time across the board, this new circular saw boasts performance like none other and can make up to 750 cuts in 90 mm x 45 mm pine stud on one 12.0 Ah battery charge.

“When we introduced the first 190 mm cordless 18V circular saw in 2013, it completely changed the way professionals saw what cordless circular saws were capable of,” said Richard Powell, Product Manager for Milwaukee Tool. “Fast forward to today and our leadership in cordless technology has advanced to such a point that we can now deliver a 190 mm circular saw on an 18V system that cuts faster than the leading corded units on the market. From the ground-up redesign of our electronics, to the manufacture of a powerful new motor and a brand-new powerhouse – the M18 REDLITHIUM-ION HIGH OUTPUT HD12.0 Ah Battery – we were able to combine three game-changing technologies to provide users with the most capable circular saw we have ever introduced to market.”

True to all M18 FUEL solutions, the new M18 FUEL Circular Saw combines three exclusive innovations – the POWERSTATE brushless motor, REDLITHIUM-ION battery pack and REDLINK PLUS intelligence. However, to deliver the first 18V circular saw that generates the power of a corded, Milwaukee® reengineered these critical cordless components to deliver the very best performance catered to this tool and its applications.

Milwaukee® created a brand-new POWERSTATE Brushless Motor for this Circular Saw, which delivers 5,800 RPM to rip through tough applications without bogging down. Milwaukee® also redesigned from the ground-up the REDLINK PLUS Intelligence featured in this tool, utilising electronics never used before in power tools. This newly designed REDLINK PLUS Intelligence package ensures maximum performance of the tool under load and prevents against overload and overheat.

When equipped with Milwaukee®’s new M18 REDLITHIUM-ION HIGH OUTPUT HD12.0 Ah Battery, the Circular Saw can power through up to 750 cuts on just one battery charge, eliminating the hassle of cords or constant switching-out of multiple battery packs, while exceeding the performance of higher voltage solutions in the industry. The new HIGH OUTPUT HD12.0 Ah Battery provides 50% more power, runs 50% cooler, and delivers 33% more run-time than the M18 REDLITHIUM-ION HD9.0 Ah Battery. In conjunction with REDLINK PLUS Intelligence and the POWERSTATE Brushless Motor, the HIGH OUTPUT Battery allows users to push the Circular Saw hard and work all day – delivering more work-per-charge than any other professional power tool system.

The new M18 FUEL Circular Saw also features a cast magnesium construction to reduce the weight of the tool without sacrificing the legendary durability Milwaukee® has long been known for.

Milwaukee® is committed to improving productivity by providing performance-driven and trade-focused solutions so users can perform an entire day’s work on one battery system. The new Circular Saw is fully compatible with the entire M18 line, now offering more than 135 power tool products, and is a true testament to Milwaukee®’s focus on investing in game-changing technology that truly delivers breakthrough solutions for users.

* M18 FUEL is engineered for the most demanding tradesmen in the world. Delivering unrivaled performance, all M18 FUEL products feature three Milwaukee®-exclusive innovations - the POWERSTATE Brushless Motor, REDLITHIUM-ION Battery Pack and REDLINK PLUS Intelligence Hardware and Software - that deliver unmatched power, run-time and durability on the jobsite. Simply put, M18 FUEL tools are the most powerful 18V cordless tools in their class.
